11 Claim.

This invention has to do with the brackets which are used to support the spring wound curtain rollers at the windows of automobiles, and is particularly concerned with a novel bracket construction for use in that type of assembly wherein a retractable journaling trunnion is provided for the roller to facilitate application and removal oi the latter.

One of the objects of the invention is to provide a bracket of improved construction which has a roller-supporting member retraotably mounted therein.

Another object is to provide a roller-supporting member of improved construction which is easy to apply to the bracket.

Other more specific objects and advantages will be apparent to those skilled in the art upon a full understanding of the construction, arrangement and operation of the parts which together constitute the improved bracket.

Three different structural embodiments of the invention are presented herein by way of exemplification, but it will of course be appreciated that the invention is capable of embodiment in still other structurally modified forms coming equally within the scope of the appended claims.

In the accompanying drawing:

Fig. 1 is a top view of a bracket constructed in accordance with the invention, showing a curtain roller associated with the bracket;

Fig. 2 is a hofizontal section through the bracket and roller;

Fig. 3 is an end view of the bracket;

Fig. 4 shows, in separated relation, the parts which are adapted to be combined to form the retractable trunnion;

Fig. 5 is a section through a modified form of the bracket;

Fig. 6 shows, in separated relation, the parts which are adapted to be combined to form the trunnion for the bracket illustrated in Fig. 5;

Fig. '7 is a section through another modified form of the bracket;

Fig. 8 shows the trunnion for the bracket which is illustrated in Fig. 7; and

Fig. 9 is asection through the head of the bracket shown m Fig. 7, taken on the line 9-9 of Fig. 7.

The bracket which is shown in Figs. 1 to 4 inelusive consists of an Lshaped sheet metal stamping 1D and a cup-shaped sheet metal stamping 11. One leg 12 of the stamping 10 is provided with holes 13 for the reception of the usual attaching screws, while the other leg 14 terminates in a circular end portion 15, which portion is provided at its center with an aperture 16. The cup-shaped stamping 11 has its rim 1'7 intumed about the edge of the circular portion 15 of the stamping 10 and forms with the same a hollow head 18. The stamping 11 is provided at its center with an aperture 19 which is arranged in align- 1 ment with the aperture 16.

A trunnion 20 is slidably mounted in the head 18, in the apertures 16 and 19 in the outer and inner walls of the head, with the inner end: 21 of the trunnion projecting a substantial 'distance beyond the inner wall into a journaling socket 22 in one end of the associated roller 23. The other end of the trunnion projects slightly beyond the outer wall of the head and terminates in a finger piece 24 which fits closely up against the outer wall. The trunnion 20 is surrounded, within the head of the bracket, by a coil spring 25, which spring is confined between the outer wall of the head and an annular rib 26 on the, trunnion. The finger piece 24which is used-in retracting the trunnion against the action 01' the springserves to limit the axial movement of the trunnion toward the roller 23, while the rib 26 limits the movement of the trunnion in the gage the projecting end 21 of the trunnion from' the socket 22 in the roller. i As will be observed in Fig. 4, the trunnion 20 is made up of two parts, one a tube 27 andthe other a headed pin 28. The tube 27 is upset intermediate its length to form the annular rib 26v on the trunnion. In assembling the bracket,- the tube 27 and the spring 25 are placed in posi-i tion before the cup-shaped stamping 11 is'attached to the stamping 10. After the stamping i 11 has been attached, the pin 28 is inserted in the tube 2'7 and the end 29 of the pin is then riveted out over the end 30 of the tube. The head of the pin forms the finger piece 24;

In the modification which is shown Figs. 5 and 6 the hollow head formation of the-bracket is substantially the same as in the first described embodiment of the invention but the retractabletrunnion 31 is made in a somewhat 'diiferent Way; 0 In this form of the invention, the trunnion can:

sists of a solid pin which is provided intermediate its ends with an annular rib 32. The outer end 33 of the pin is reduced in diameter and is adapted to receive a small washer 34 after all of the other 105$ trunnion for use in retracting the latter from 1103 opposite direction when it is retracted-to disen 1 the socket in the roller against the action of the spring.

In the modification which is shown in Figs. '7 and 8, the spring is dispensed with and the trunnion 36 is made in one part instead of two. In this embodiment, the cup-shaped stamping 3'? is shown as countersunk about the aperture 38 in order to provide a recess for the reception of the finger piece 39 on the outer end of the trunnion. The trunnion 36 is prevented from being entirely withdrawn from the head of the bracket by means of a pair of diametrically opposed tongues 40 on the stamping 37, which tongues press more or less resiliently with a certain amount of friction against the shank of the trunnion and are adapted to engage within abrupt wall notches 41 in the shank after the trunnion has been retracted far enough to clearthe end of the roller. The frictional engagement of the tongues 40 with the shank of the trunnion is preferably-such as to prevent any likelihood of thetrunnion working out of the roller except when forcibly withdrawn from the same by means ofthe finger piece 39. In this form of the ini' ven'tion the trunnion 36 can be inserted in the head of 1 the bracket after the latter has been fully assembled, and when once inserted it cannot be withdrawn beyond a certain point, which point is determined of course by the location of the notches 41with respect to the tongues 40.
